Product: Microsoft InTune Company Portal
Scenario: User is unable to authenticate when with InTune when they enter their e-mail address and active directory password.
Note: Multi-factor authentication is being used when enrolled in Microsoft InTune.
Additional information: The user was enabled with Multi-factor authentication with their e-mail address and then their username.
Things to try next: Disable Wi-Fi and authenticate with InTune with a cellular network via a hotspot from another phone.
OS: Arnold device
Confirmation: I confirmed that the user can login to the web based version of Microsoft InTune.
Things to be tried next, authenticate with InTune on another device, let say another Android or an iOS device.
I was also thinking of looking up Microsoft InTune FAQ
Any more ideas?
